Among these genes, MYO6, which encodes an actin-based motor protein that is upregulated in various types of cancer,19, 20, 21, 22, 23, 24 has been widely reported to contribute to tumor cell migration and metastasis.25, 26, 27, 28, 29, 30 Therefore, we selected MYO6 for further investigation and measured its expression in GC cell lines at both the mRNA and protein levels. The gene discussed is MYO6; the disease is cancer.
